Features:
- Supports up to four independent vibration monitoring channels with dual Keyphasor inputs for accurate speed and phase tracking.
- External termination architecture improves field wiring accessibility and maintenance efficiency in complex installations.
- Performs signal filtering and integration while providing buffered outputs with short-circuit protection for safe diagnostics and testing.
Bently Nevada 126623-01 plays an important role in machinery protection systems where accurate vibration monitoring is required to maintain equipment reliability. High-speed rotating assets such as aeroderivative gas turbines depend on continuous condition monitoring to detect abnormal operating conditions before equipment damage occurs. The module provides the interface needed to acquire critical vibration information from field sensors.
Within turbine monitoring applications, 126623-01 receives signals from velocity transducers, accelerometers, and Velomitor sensors installed on machinery casings and bearing locations. Signal conditioning functions help prepare raw vibration measurements for analysis while dual Keyphasor inputs support precise shaft rotational tracking. Such capabilities contribute to improved diagnostic accuracy for complex rotating equipment.
Bently Nevada 126623-01 is frequently deployed in power generation facilities, oil and gas installations, refineries, and pipeline compressor stations. With a typical power consumption of 7.7 watts, an Aero GT I/O input impedance greater than 95 kΩ, and operation across a wide industrial temperature range, the module delivers dependable performance in demanding environments where machinery availability and protection are critical operational priorities.
The 126623-01 Bently Nevada Aero GT I/O Module External Termination may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
